Can anybody give me an accurate max towing weight that will be safe and not destroy my transmission?
Also, are there cost-effective things I can do to the truck to increase it's safe towing ability?
The vehicle is 14 years old so much depends on engine size/has it been abused or serviced per GM schedule/high millage/etc.
The wife just sold her '06 1500 crew cab chevy Z71 5.3 3.73 axle/295 hp. It had a 7400 lb tow rating but I sure wouldn't want to pull a 7000 lb RV trailer with it.
I used it to pull a 10k car hauler/tractor which grossed around the 6800-7000 lb range with the loader and box blade removed.
It did ok on the flats but I sure wouldn't want to pull a tall 6k-7k boxy RV in the hills or mountains or into high heads winds like we have out here.
For a tow vehicle that old/low hp engine I would stay under 5k-6k actual wet weight.
